0104202TierneyThe recent Cerro Grande and Viveash wildfires in New Mexico provide a unique opportunity to study the early effects of intensive regeneration efforts on two distinct forest types. Over 720,000 poinds of seed, most of which was non-native grasses, was applied to the Cerro Grande burn site over this summer. Similarly, 230,000 pounds of seed were also applied to the Viveash site. Review of the literature suggests that ecological studies evaluating the effects of reseeding, particularly with non-native species, have not been conducted in such southwestern forest ecosystems. This project will monitor the establishment and distribution of introduced, seeded and post-fire native emergent species in the first two growing seasons following the wildfires. Data collected in this exploratory study will be used to test spatially explicit models that predict patterns of distribution and persistence among introduced and native plant species in seeded and unseeded burned areas. These models are useful in examining the long-term effectiveness of reseeding and the effects of introducing non-ntaive species on patterns of recovery and succession in mid-elevation Ponderosa pine and high-elevation spruce/fir forest systems.

0104202Tierney 新墨西哥州最近发生的 Cerro Grande 和 Viveash 野火提供了一个独特的机会来研究强化再生工作对两种不同森林类型的早期影响。今年夏天，超过 720,000 磅的种子（其中大部分是非本地草）被施用于 Cerro Grande 燃烧现场。同样，230,000 磅种子也被施用于 Viveash 场地。对文献的回顾表明，尚未在西南森林生态系统中进行评估重新播种（特别是非本地物种）影响的生态研究。该项目将监测野火后前两个生长季节引入、播种和火后本地挺水物种的建立和分布。这项探索性研究收集的数据将用于测试空间显式模型，该模型预测播种和未播种烧毁地区引进和本地植物物种的分布和持久性模式。这些模型可用于检查重新播种的长期有效性以及引入非本地物种对中海拔黄松和高海拔云杉/冷杉森林系统恢复和演替模式的影响。
